Application lefl September 26, 1916.

To all ywhom 'it may concern: f

Be it known that we, GEORGE A. Prisoner and RICHARD A. UHLrN, both citizens ot the United States, vresiding at Seattle, in the county of King and State of Vilashington, have invented certain new and useful lmprovements in Oil-Burner-Air-Supply Regulators, ot' which the 'following is a speeltication.

rl`his invention relates to oil burners of the wickless class which, by their own heat, vaporize the oil then introduce air and burn the gaseous mixture. To produce complete combustion and the consequent intense heat the conditions to be considered are, the mixture of oil-vapor and air in due pro-v portions, either at the sea level, on mountain tops, or at any intermediate height, and under the varying conditions of diderent styles of burners and the different service they perform.

rlhe object of our invention is to adapt an air supply regulator to meet these various requirements.

To this end, our invention consists in the construction and combination of parts hereinafter more fully described, and particularly stated in the claims, reference being had to the accompanying drawingsl in which;

Figure l represents in side elevation, partly in longitudinal, vertical section an oil burner airy supply regulator with the gage-rod in service, according to our invention. Fig. Q represents the air intake tube and the air gate in position for service.

Numeral l represents the oil vapor supply pipe leading into jet 2, the delivery*A nozzle 3, of Which-shown in Fig. 2 as discharging a. spray ot' vapor-is in central line of the gate tube ll, which communicates through a passage l, with the usual mixing chamber a portion of the bottom of which is shown at 5. The jet 2 with its base cap 6 its side cap 7 and its lever 8 for operating a cleaning device is not peculiar to this invention. The intake tube 9 is open at both ends and removably engages the jet 2 in a neat cylindrical fit at 10. The gate tube ll is screw-threaded into the upper side of the intake tube 9, and tits movably into the passage 4 in order that it may berotated to screw to and from the nozzle 3, thus decreasing or increasing the size of the opening for the free passage of air into it.

gage rod- 12 in tapering or wedge-like form,

with indices 13 marked at intervals upon it, 1s adapted to be inserted as shown 1n Fig. l,

between the ends of the gate ll and the noz#- zle 3 to locate the adjustment of the gate, then. it is to be removed leaving free passage-as shown in Fig. 2,-for the jet of vapor from the nozzle 3 to be forced under due pressure into the tube 1l, drawing in with it air in such quantity as the opening at the end of the gate will permit. The gage-bar may have two, four, or more sides marked with scales adapted to units of different styles of measurement. The marking shown on the in the-drawing may indicate feet above level, and the gage set shown would be suitable to admit the required amount of air at an altitude of 3750 feet when a nozzle is used having a delivery outlet .016 of an inch in diameter, as indicated on this side of the gage near its end. Burners for some purposes require a larger nozzle opening, the diameter of which would be marked on the same side of the gage as the corresponding scale numerals. For such purposes the gage rod mayhave any suitable number of sides to receive the required markings to indicate the proper set 'ot' the air gate l1.

ln all the varying conditions the position of the graduating marks must be located upon the gage by actual experiment at a considerable expense of time and labor, but when once established, any number of gage rods may therefrom be graduated, s0 that a burner to meet the requirements of any customer may be quickly set to produce the best results, and if the customer be provided with a gage he can easily readjust his burner if he should move to a different altitude or if conditions aliecting `the air ,intake were otherwise changed. If each purchaser of an oil burner equipped with this device be instructed. in this simple mechanical means of properly adjusting it he will find it to vvork with more economy and generally with better results than burners not so.equipped.

lVe claim:

l. ln an oil burner air supply regulator, the combination with an air and oil-vapor mixing chamberhaving a passage through its bottom anda delivery nozzle for oilvapor located to deliver into the said aperture, of an intaketub.I open at both ends and fitted upon the said nozzle for free removal,
